26 Claims.

This invention relates to typographical composing machines, such asLinotype machines of the general organization'represented in LettersPatent of the United States No. 436,532 to O. Mergenthaler, whereincirculating matrices are released from a magazine in the order in whichtheir characters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type characters thereon, and the matrices thereafterelevated and returned through distributing mechanism to the magazinefrom which they started.

More particularly, it relates to machines of the kind known to the tradeas model 9, wherein a series of superposed magazines are mounted in afixed supporting frame, and wherein the assembling mechanism includes avertically adjustable throat .which may be brought into operativerelation with any selected magazine by operating a hand lever locatedadjacent the keyboard. The magazines are slidably mounted in thesupporting frame so that one or another may be removed therefrom whendesired for interchange, and the assembling mechanism is hingedlymounted to permit it to be swung out of the way preparatory to themagazine removal operation. Heretofore, in effecting the interchange ofa magazine, the services of a skilled mechanic have been demanded andthe time ordinarily consumed has been objectionably long, particularlyin modern composing rooms where the question of time s an importantfactor.

The present invention is intended primarily to improve these conditionsand contemplates means whereby the uppermost magazine of the series maybe quickly and easily removed for interchange by the operator of themachine and without the aid of a skilled mechanic. To that end, thisparticular magazine is supported in a subsidiary frame which overliesthe magazine and which is upwardly movable to carry the magazine to aposition where it may be removed without di turbing the assemblingmechanism. To permit its removal, the magazine is slidably mounted inits supporting frame and held positioned therein by a latch bar which iseasily accessible'when the magazine is in its raised position.

In the preferred embodiment illustrated, the supporting frame ishingedly mounted at its upper end in fixed brackets, and near its lowerend and at its opposite sides it is provided with a pair of lifting camswhich engage corresponding antithe machine frame.

friction rollers located directly beneath them in The lifting cams areattached to a horizontal rock shaft journalled in the magazinesupporting frame and are adapted, by a partial turn in oppositedirections, to raise and lower the magazine to and from a position abovethe assembling mechanism. Operation of the rock shaft is accomplished bymeans of a pair of arms pinned thereto and which ordinarily occupy aninconspicuous position out of the way alongside the magazine supportingframe. When it is desired to remove the magazine, these arms are swungforwardly into a position where they will serve not only to facilitatethe removing operation but also to support the magazine at the front ofthe machine in the proper vertical position for handling.

As a means of safety, the present improvements also include a device forlocking the rock shaft against operation while the assembler throatoccupiesits uppermost position,this in order to prevent interferencebetween the lower end of the magazine and the assembler throat as theformer is lifted for removal. The construction of this device and themanner of its control will best be understood from the detaileddescription to follow.

Each magazine is providedwith a series of eS- capements to control therelease of the matrices therefrom, and the several series of escapementsare actuated by a single set of reeds mounted in a vertically slidingsash frame which carries the assembler throat and whichis movableupwardly and downwardly by operation of the hand lever before-mentioned,so as to locate the reeds'in engaging relation with the escapements ofone magazine or another as desired. This single set of reeds is actuatedby a set of main reeds which are in turn actuated through suitableconnections from the keyboard in the usual way. In order to engage anddisengage the single set of reeds with and from one or the other of theseveral series of escapements, they are mounted as usual in a secondaryframe movable horizontally in the sash frame, the forward movement ofwhich disengages the reeds from the escapements of the operativemagazine preparatory to the shifting of the sash frame, and the rearwardmovement of which engages the reeds with the escapements of anothermagazine after the shifting of the sash frame, these respective forwardand rearward movements of the secondary frame simultaneously disengagingthe reeds from and engaging them with the keyboard connections.

To locate the sash'frame in its diiierentverti cal positions, theadjustable hand lever is provided with a latch dog which is arranged inengaging relation with a notched sector plate and which is actuated by apivoted grip element associated with the hand lever and controlling themovements of a second lever for operating the escapement reed frame. Ingrasping the hand lever, the second lever will be actuated through thegrip element first to retract the reed frame and then to disengage thedog from the sector plate so as to free the hand lever and permit it tobe moved to any selected position determined by the notches in thesector plate. When the hand lever is released and the dog allowed toenga e the selected notch, both levers will be locked against movementand, through intervening rack and gear mechanism, the assembler throatas well as the escapement reeds will be located in operative relationwith the corresponding magazine.

Ordinarily, the sector plate in the later Model machines s 0 arranged ththe o h s th re n are o t of the l ne f vis o o the ov a or n ons era leca and ski l must e exerci e in find n qu ckl h appropri te notch for agiven adjustment. Here again the time element enters as a governingfacto and, as an additional feature of the present invention, it isproposed to facilitate the operations above indicated. To this end, thevertical movements of the throat and sash frame are controlled from acrank shaft operable at will and which is adapted by a single revolutionto effect the individual adjustments thereof. As it completes onerevolution, the crank shaft is locked against accidental movement .bymeans of a spring-actuated latch member controlled by a hand lever whichis arranged conveniently adjacent the crank shaft and also controls theforward and rearward movements of the escapement reed frame, theintermediate connections as herein shown comprising a bell crank leverand a. tubular shaft which is associated with the rack and gearmechanism for actuating said frame. The crank shaft, on the other hand,is connected through a vertical gear shaft and a short foreand-aft driveshaft to the usual horizontal shaft for actuating the rack bars of thesash frame. one arm of the bell crank lever is connected to the latchmember and the other is arranged to engage one end of the tubular shaft,which latter is mounted on the horizontal shaft for a limited axial aswell as a rotary movement. The latch member is arranged to engage asingle notch formed in a collar fastened to the vertical gear shaft and,by such engagement, it is adapted to lock the crank against rotationthrough the connecting gears. When the hand lever is operated, the latchmember will be withdrawn from engagement with the collar to release thecrank shaft, and the tubular shaft at the same time will be actuated tomove the escapement reeds forwardly to their inactive positionpreparatory to the rotation of the crank shaft and the verticaladjustment of the sash frame and throat. If only a minimum adjustment isrequired (i. e. from one magazine to the next) the pressure on the handlever may be relieved as soon as the crank shaft starts its revolution,so that the latch member may be allowed to reengage the notch in thecollar and the reeds allowed to resume their active position as thecrank shaft completes its revolution. On the other hand, if a greateradjustment is to be made, it will then only be necessary to calculatethe number of revolutions of the crank shaft required and. release thehand lever at the start of the last revolution. The crank shaft, ofcourse, is provided with a handle which normally occupies a definiteangular position so as to indicate to the operator when he has aboutcompleted a turn and therefore when to manipulate the hand lever.

In the accompanying drawings the invention has been shown merely inpreferred form and by way of example, and it should therefore beunderstood that the invention is not limited to any specific form orembodiment except insofar as such limitations are specified in theappended claims.

The matrices X are stored according to font in four superposedmagazines, the uppermost one of is designated A and the remaining threeA Each magazine is provided with a series of escapements a, and any oneof the four may be selected for use at will by the operation of avertically adjustable sash frame B, which latter gives support to athroat B for conducting the matrices as they are released from theselected magazine into the vertical channels of a front plate C. Thesash frame B is slidable in a rectangular frame member P and alsocarries a secondary frame D wherein is mounted a single set of reeds Dadapted to actuate one series of escapements or another according to theadjusted position of the sash frame. The reeds D are operated from thekeyboard (not shown) through a main set of reeds E and a correspondingset of pivoted levers E mounted in the machine frame (see Fig. 10). Thevertical movements of the sash frame B are accomplished by the rotationof a horizontally disposed shaft B journalled in the frame P andprovided at its opposite ends with a pair of pinions B meshing with acorresponding pair of vertical rack bars B secured to the sash frame atopposite sides thereof. As best shown in Fig. 9 the secondary frame Dcomprises generally the two upright side members D and a pairof toothedconnecting cross bars D which latter project beyond the side members Dinto fore-and-aft grooves b formed in the sash frame, so that they maybe moved rearwardly and forwardly to engage and disengage the reeds Dwith and from the levers E and the chosen series of escapements a. Toinsure true alignment of the throat B with a se-:

lected magazine and the reeds with the escapements, the upperextremities of the side members D of the secondary frame are formed withlips or hooks (1 adapted in the rearward position of said frame toengage corresponding notches a formed in the rigid side bars of theindividual magazines. The forward movement of the secondary frame D iseffected against the influence of four small compression spring d by apartial rotation of a short tubular shaft D mounted on the horizontalshaft B the shaft D being provided with a pinion D adapted to raise andlower a single rack bar'D which meshes with a pair of elongated pinionsD associated, one with each of the toothed cross bars D As thus fardescribed, the parts and their mode of operation are or may be the sameas embodied in commercial machines of the type described or as shown inthe patent to D. S. Kennedy No. 1,981,753 to which reference may be madeif desired. It may also be noted that, as shown best in Fig. l, theassembling mechanism as a whole is hingedly mounted in a fixed bracket 0at the right of the machine so that it may be swung out of the way foraccess to the magazines or when? ever it is desired to remove one of thelower magazines A Turning now to the principal feature of the presentinvention, that is, the manner of mounting the uppermost magazine A topermit its removal at the frontof the machine without disturbing theassembling mechanism, the magazine (Figs. 1, 6, 7 and 8) is supported byan overlying frame member F pivoted at its upper" end in brackets Orising from side members 0 of the main frame and provided near its lowerend with a horizontal rock shaft)? which projects outwardly at bothsides beyond the frame member to carry a pair of lifting cams F and alsoa pair of actuating arms F The supporting frame F, on its under side, isformed with a pair of fore-and-aft T-shaped grooves f, and" the magazineA on its top side is provided with tributing mechanism and the upper endof the magazine so that the distribution of matrices thereto may becarried on in the usual way.

The magazine A is positioned in the support ing frame F in afore-and-aft direction by meansv of a centrally located latch member G(see Fig. 2) fastened to the rear end of a short rock shaft Cr andarranged to engage the forward cross rib A of the magazine. The shaft Gis rotatably mounted in ears 0 and gr depending from a plate Gr securedto the supporting frame and is provided at its front end with a handle Gwhich is movable in opposite directions to engage and disengage thelatch member G with and from the magazine. A stop pin 9 projectinginwardly from the handle above the plate G limits the movements of thehandle and stops the latch member G in its active or inactive position.The plate G is mounted on the frame F by means of clamping screw andslot connections g so that it may be adjusted longitudinally whendesired to regulate the position of the magazine relatively to itssupporting frame and the assembling mechanism. The adjustment of theplate is effected by a set screw 9 mounted alongside the shaft G in thefront depending ear 9 of the plate and anchored in the frame F againstendwise movement by a pin 9 which engages an annular groove formed inthe shank of the set screw. When an adjustment is required, it is merelynecessary to loosen the clamping screws g turn the set screw 9 one wayor the other to shift the plate G2 and latch member G to the properposition, and then retighten the clamping screws.

With the parts in the full line position shown in Fig. 1, the magazine Ais sustained in its operative position through the engagement of thelifting cams F with a pair of anti-friction rollers O mounted invertical bracket plates 0 rising from the side members 0 of the mainframe. When it is desired to remove the magazine, the actuating arms Fare swung forwardly to the position indicated by the broken lines inFig. 1, so as to rotate the rock shaft F and through the lifting cams Fraise the supporting frame F and the magazine above the assemblingmechanism, the movement of the parts involved in this operation beinglimited bythe engagement of the rollers O in corresponding recesses)formed in the outer edges of the cams F (see Fig. 6). The short rockshaft G may then he turned by means of the handle G to disengage thelatch member G from the cross rib A of the magazine and the latter thusallowed to slide forwardly out of the frame F onto the arms F which nowserve not only to facilitate the removing operation but also to supportthe magazine thereafter in a convenient vertical position for handling.In

this connection, it may be mentioned that the arms F are capable ofgiving the desired verticalisupport to the magazine through theengagement with the customary hooks at their extre'mities with the uppermagazine reinforcing rib A which for the purpose is extended (see Fig.7) beyond the opposite sides of the magazine A. After a new magazine hasbeen pushed into the supporting frame F and locked therein by the latchmember G, the arms F are swung backwardly to lower the magazine intooperative position under control of the cams F A cover plate F fastenedto the supporting frame F, serves to conceal from view certain movingparts carried thereby and thus to improve the general appearance of thewhole structure.

As a safety feature, to prevent accidental release of matrices from themagazine A during its removal and replacement, it is proposed to lockthe escapements a thereof against actua-V;

tion as the magazine is raised preparatory to its removal and to unlockthem for normal operation as'the magazine thereafter is returned to itsoriginal or operative position. Accordingly, the magazine is providedwith a halfround rock shaft a (Fig. 10) mounted in the escapement frameand extending completely across the magazine in engaging relation withthe escapements. The rock shaft 11 is operable by means of a crankelement a secured to one end thereof, and is adapted by a quarter turnin opposite directions to lock and release the escapements a. The crankelement a is provided with a pull spring a which tends to turn the shaftin the appropriate direction to engage the escapements, and an angularbracket plate (2 which extends inwardly from the contiguous frame memberinto the path of the crank element a is adapted through its engagementtherewith to turn the shaft against the tension of the spring a in theother direc tion to release the escapements. In other words, when themagazine is lowered into operative position, the rock shaft will beturned to its inactive position by the engagement of the crank elementwith the bracket plate; Whereas, when the magazine is raised preparatoryto its removal and as the said element is carried out of its engagementwith the bracket plate a the spring a will be permitted to turn theshaft into locking engagement with the escapements. A stop pin a whichprojects outwardly from the escapement frame in engaging relation withthe crank element a serves at the time to limit the rotation of the rockshaft.

As another safety feature, to prevent lifting of the magazine A forremoval while the sash frame 3 and the assembler throat B are located inoperative relation therewith, the rock shaft F for the reasons alreadystated and as shown in Fig. l, is locked at this time against operationby means of a horizontally disposed lever H, the longer arm H of whichis formed with a hook-shapedend portion h arranged to engage a stud fprojecting outwardly from an arm F depending from the shaft F The leverH is pivoted to the side frame member 0 and is operable from the sashframe B through a second lever E (Fig. 9) pivoted to the frame of theassembling mechanism and arranged to en-' gage'the shorter arm H of thelever 1-1. When the sash frame B is lowered out of its operativerelation with the magazine A, the lever H is allowed to disengage thelever I-I, so that the hook h of this lever may drop by gravity out ofits engagement with the stud f and, conversely, when the sash frame isagain shifted to its uppermost position, it actuates the lever 1-1 andthrough it rocks the lever I-I so as to reengage the hook with the studf Stop pins h and 71. sustain the levers H and H respectively, in theirinactive position.

In the present instance and as before stated, the aforementioned shorttubular shaft D is mounted on the shaft B for axial as well as rotarymovement, and its operation is controlled from a hand lever J dependingfrom a rock shaft J to which it is pinned (Fig. 5). Adjacent the handlever, the rock shaft J is provided with a bell crank lever J one arm ofwhich i forked to straddle the shaft B and engage a flanged collar 1)formed at one end of the tubular shaft D and the other arm of which isconnected by means of a vertical link J to a pivoted latch bar K, thepurpose of which will presently appear. The

tubular shaft D (see Fig. 14) is connected to the shaft B by means. of apin d and a short spiral slot 01 formed in the collar D so that, bymoving the shaft D endwise, it will be turned at the same time toactuate the vertical rack bar D through th pinion D which latter iskeyed by means of a tapered pin d to the other end of the shaft D Thepin (1 passes through a slot 1) formed in the shaftB and madesufficiently long and wide to permit, not only the endwise movement ofthe tubular shaft, but also the partial turning thereof necessary tooperate the rack bar D A pull spring d anchored to the pin (1 andconnected to the flange of the collar D holds the tubular shaftyieldingly in its normal angular position in the shaft B and asdetermined by the pin d It will now be seen that, by moving the handlever J from its normal position, as shown by the full lines in Fig. 9,to that indicated by the broken lines in said figure, the shaft D willbe pushed by the forked arm of the lever J a limited distance along theshaft B and simultaneously turned against the influence of the spring (1in the appropriate direction to raise the rack bar D and, through theintervening connection before described, move the escapement reed frameD forwardly to its inactive position. As the hand lever is released, thesprings 01 and the spring d act concurrently to lower the rack bar D andrestore the frame D and shaft D to their original positions.

As another feature of the present invention, the operation of the shaftB in adjusting the sash frame D from on magazine to another, iscontrolled from a short fore-and-aft shaft L mounted in a bracket Psecured to the rectangular frame member P of the assembling mechanism,said shaft being adapted by a single revolution in one direction or theother to effect the individual adjustments of the sash frame. As bestshown in Fig. 4, the shaft L is provided with a crank handle L andoperatively connected through a pair of bevel gears L to the lower endof a vertical shaft L also mounted in the bracket P and which issimilarly connected at its upper end by means of another pair of bevelgears L to a short drive shaft L The shaft L is provided about midway ofits length with a collar L formed with a single notch Z which isarranged in engaging relation with the beforementioned latch bar Kwhereby the crank shaft may be locked against rotation. Motion from thedrive shaft L is imparted to the horizontal shaft B through the mediumof a worm wheel L and a gear L integrally connected together androtatably mounted on a stub shaft L the worm wheel L engaging with aworm L keyed to the drive shaft, and the gear L meshing with a pinion Bsecured to one end of the shaft B The hand lever J, as may be observed(Fig. ,4), is arranged conveniently adjacent the crank handle L and, dueto the leverage obtained as well as the ratio of the gearing and theWorm drive, an adjustment of the sash frame B may be quickly and easilyaccomplished even though both hands are required to perform theoperation, it simply being necessary, first to swing the hand lever J alimited distance in the appropriate direction to move the escapementreed frame D to its inactiveposition in the manner above described, andthen to turn the crank handle L through one, two or three revolutions toeffect any desired adjustment of the sash frame. By the first operation,the latch bar K .will be automatically disengaged from the collar L and,as soon as the second operation is started,

has been turned through one complete revolution, at which time the notchl in the collar L will again register with the latch bar K (compareFigs. 4 and 5). Now, as the bar K snaps into the notch l, the shafts Land L willbe locked against rotation and the sash frame located in itsnewly adjusted position. Undue strain on the locating pin d for thetubular shaft D by operation of the hand lever J is countermanded bymeans of -a banking screw 7' (Fig. 9 projecting laterally from saidlever and arranged to engage a portion of the bracket P Also, the crankshaft L, the vertical shaft L and the drive shaft L are all providedwith thrust bearings L to facilitate their movements and reduce thephysical efiort required to operate the crank handle L It is believedthat the variou parts, their construction and mode of operation havebeen sufficiently described and that any further description would besuperfluous.
